The Masked Singer season 9 semi-finals aired on Fox on Wednesday, May 10, at 8 pm ET. The three remaining contestants, California Roll, Macaw, and Medusa, competed for a spot in the finals in the episode. Initially, they all sang individual songs before reaching the battle royale, where the three singers performed on Bruno Mars’ Runaway Baby.California Roll, who was the winner of the first group in week three, dazzled the audience with their group performance on Runaway Baby and Kelly Clarkson’s Breakaway. The five singers, who are all in sushi masks, gave electric performances, just like their week 3 performance of Billy Joel’s Uptown Girl.

Jenny guessed that the California Roll could be the cast of Broadway Musical or Pentatonix. Nicole said that the singers might be the cast of Spring Awakening or Hamilton, while judge Jen took it too far by guessing that the California Roll was the cast of In the Heights. The Masked Singer fans were not hoping that California Roll would be eliminated despite such a good performance. However, the studio audience and judges voted them off and they were later unmasked as the music band Pentatonix. Fans were very upset by this and even doubted if the show was show was rigged as the group performed much better than Medusa.Jaiden VonFlatern@JaidenVonFlate1The California Roll didn't deserve third, they deserved first!!!
